SAFETY-GUARD FOR RIP-SAWS.

SPECIFICATION forming part of Letters Patent N0. 528,262, dated October30,1894.

Application filed January 31, 1894:. Serial No. 498,559. (No model) 7 Toall whom it may concern.-

Be it known that I, GEORGE A. SHIELDS, a citizen of the United States,and a resident of Anderson, in the county of Madison and State ofIndiana, have invented certain new and useful Improvements inSafety-Guards for Rip-Saws; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled.

in the art to which it appertains tomake and use the same, referencebeinghad to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

[5 Figure 1 of the drawings is a side elevation of the inventionapplied. Fig. 2 is a top plan View of the invention. of the splitter andsocket. Fig. 4 is a bottom view of the socket. Figs. 5 and 6 are detail.20 views showing modified forms of the splitter, and Fig. 7 is asection on the line m m, Fig. 2.

This invention has relation to certain new and useful improvements insafety guards for rip-saws; and it consists in the novel constructionand combination of parts, all as hereinafter described and pointed outin the accompanying claims.

The object of the invention is to provide a simple, convenient, andpractical device,

0 adapted to be supported over the exposed portion of a rotary saw, andthereby greatly lessen the chances of injury to the operator, either bycontact therewith, or by flying missiles thrown from the saw.

5 Referring to the accompanying drawings, the letter A designates a sawtable of the usual form, and B a rotary saw.

Set in the table at the rear of the saw, is a socket plate C, adapted toreceive and sup- 0 port a vertical splitter D. In the drawings, I haveshown the socket plate 0 as having a groove or guide a, for thehorizontal base I) of the splitter, and an L-shaped slot 0, which isengaged by a pin 61 projecting from the under side of the-.said base b.Other suitable forms of socket plate may however be employed.

t Figs. 5 and 6 show different forms of spliters.

The upper end portion of the splitter en- Fig.3 is an end view gages alongitudinal slot-e in the end portion of a horizontal rod E, and isheld therein by means of a nut and washer F, on the threaded end of saidrod. The forward end portion of the said rod is adj ustably held in acoupling sleeve G by a screw g. In the other end portion of said sleeveis held one end portion of a second horizontal rod H, which is also adjustable and is held by a screw h. The opposite end portion of the rod His held in a clamp I which also holds the guard plates J, J. Said clamphas a semi-cylindrical groove j, which receives one-half of the rod,

a removable wedge K being provided with a similar groove to receive theother half. The wedge K is seated in a cut-away portion of the clamp,and the rod H is adjnstably held by means of a screw is.

The guard plates J, J consist each of an arched strip, preferably ofspring metal. Their upper ends overlie each other and are held in theclamp I between the wedge K and the lower wall of the cut-away portion.Said wall is preferably somewhat convex, and the face of the wedge isconcaved to conform to the curvature of the plates. These plates arearched over the periphery of the saw, as shown, and their lower ends arebent upwardly as at j in order tofacilitate the passage thereunder ofthe board or other mate- 8o rial which is being sawed. The lower end ofthe plate J under which the material passes to the saw is bent upwardlyto a greater extent than is the oorresponding portion of the plate J,and in order to regulate the bearing tension of this portion, I hinge orpivot a baildevice L to the plate, said device at its lower end beingarranged to engage with projections or teeth l on the turned up portion.By engaging this bail with difierent of these projections or teeth itwill be apparent that the tension may be regulated.

By loosening the clamp I the guard plates may be extended or contractedupon each other to it saws of different diameters, the construction ofthe support as above described providing also for the necessaryhorizontal and vertical adjustments of the parts to correspond.

The rod H, while it may be straight, is pref- I erably bent as shown aton, so that by turning said rod the guard plates may be swung either tothe right or left of the saw.

The splitter keeps the kerf open, preventing the lumber from closing onthe saw, and also from pinching and heating the latter.

Having described my invention, what I believe to be new, and desire tosecure by Letters Patent, is-- 1. In a saw guard, the combination with asocket piece, the splitter engaging said socket, the adjustable two-partrod supported by said splitter, of the clamp I having the cut awayportion, the wedge seated therein, the ad j ust-
